Embodiment Construction

[0025] The embodiments of the present invention are described in detail below; it should be noted that the embodiments are descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0026] A full-price selenium-chromium-enriched feed for pigs, its raw material composition and weight are shown in the following table:

[0027]

[0028]

[0029] The above-mentioned raw materials are mixed evenly to become the finished feed.

[0030] The steps of the preparation method of selenium-enriched chromium yeast are:

[0031] 1. Inclined strain culture: the yeast strain resistant to high selenium and chromium (the selenium and chromium-rich yeast in pig full-price selenium-chromium-rich feed is gradually increased by the addition of selenium and chromium by Angel Lalvin D254 strain, artificially induced The mutant strain obtained is an outsourced product.) Inoculated onto a wort solid slope with a sugar content of 15% by weight, a selenium-chrom...

Abstract

The invention relates to a complete selenium-rich chromium-rich feed for pigs. According to the nutrient contents and the weight ratio of finishing pigs in different growth stages, selenium-rich chromium-rich yeast (in selenium-rich chromium-rich yeast products, the selenium content reaches 4000mg/kg, and the chromium content reaches 800mg/kg; and the additive amounts of selenium and chromium in the feed are respectively 0.3mg/kg and 0.2mg/kg) is artificially added to form a variety of complete feeds. The feed ensures the nutrient requirements of pigs, meanwhile the particular supplement of selenium and chromium is realized, and the feed is used for feeding the pigs for producing high-quality pollution-free selenium-rich chromium-rich pork. The invention is suitable for cultivation enterprises of scale and retail feeding and can generate good economic and social benefits. According to the formula, the average daily gain of finishing pigs is increased by 10-12% compared with that of ordinary pigs; the feed conversion ratio is reduced by 4% in the full-growth period; the growth and body condition is superior to ordinary pigs, the diarrhea incidence is reduced, and the disease resistance is enhanced; and the contents of selenium and chromium in pork products respectively reach 0.15mg/kg and 0.57mg/kg. Each nutritional index of the complete feed conforms to quality standards of the national concentrated feed.

Description

technical field [0001] The invention relates to the field of poultry and livestock breeding, and relates to pig feed, in particular to a full-price selenium-chromium-rich feed for pigs. Background technique [0002] Selenium and chromium are essential trace elements for the human body and are closely related to human health. Among them, selenium plays an irreplaceable and important role in resisting disease and cancer, enhancing the body's immunity, reducing cardiovascular diseases, and delaying aging. At present, 72% of my country's selenium-deficient or low-selenium areas, the dietary standard recommended by the International Selenium Society is 60 μg per person per day. According to the nutritional survey of 13 provinces and cities in my country, the daily intake of selenium for adults is only 26.63 μg, and the phenomenon of selenium deficiency is quite serious. Chromium participates in the composition of glucose tolerance factor. If chromium is deficient, glucose tolera...
